As the big bag evil half-fiend gnome had the the party at his mercy, all paralyzed by poison incense he was immune to, he decided he was going to kill one of the adventurers as an example and kill one of them every day until they told him what he wanted to know (and that the PCs actually did not know, he thought they were lying). Wondering aloud which to pick, he said "I guess I'll leave it to chance!" And then, amusing himself with his own unintentional pun, he grabbed the party priest of the god of luck, named Chance. "Yes, I will leave it to Chance to serve as an example!" and then ripped the top of his skull off, scooped out some of his brain and ate it as the others watched.
Chance was a beloved NPC, but it scene served its purpose. Before this the party was on the verge of fracturing, after this they were united in seeking revenge. (they of course escaped before another day had past and got away to gain allies and power).
